Specification of Letters Patent.

Application filed September 26, 1914. serial no; 863,706;

ing to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same;

My invention relates to improvements in br'ake'sof the type adapted foruse inconnection with traveling carriers that are slidable upon cablesand has for its primary object to provide a novelly constructed brakeattachment that may be readily and easily attached to carriers and willoperate to retard the movement of the carriers or hold the carriersagainst movement altogether, when desired.

Another object is toimprove brakes of the character described so as torender them i more practical, reliable and eiiicient in operation andinexpensive to manufacture.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out in the claims.

With reference to the drawings, wherein n "18 is detachably connectedwith the bar 5 and is designed to engage one end of the I haveillustrated the preferred embodiment of my invention as it is reduced topractice, and throughout the several views of which similar referencenumerals designate corresponding parts, Figure 1 is a fragmentary sideelevation of a part of a carrier showing my improved brake attachmentthereon and in operative position also in inoperative position in dottedlines, Fig. 2 is a sectional view taken through a part of the carrierand showing the brake lever and shoe in top plan, and Fig. 3 is a detailside elevation of the hook for supporting the lever when the brake isnot in use.

Referring to the drawings by characters of reference, the numeral 1designates a suspension cable for a carrier designated '2 as anentirety.The carrier 2 is shown only in part and is suspended by a pulley orpulleys 3. Thepulley 3 is mounted upon the cable 1 and connected withthe pulley 3 is a depending receptacle supporting arm 4. :In the type ofcarrier which is illustrated in the drawing in part, the carrierconsists of two upright members 4 and two pulleys 3.

The IqSI-ight members 4 are connected bya horizontal 'c'ross orconnecting bar 5 that is shown in part inthe drawings. 1

My improved brake attachment comprises a brake lever designated 6 as anentirety that is pivoted intermediate itsends as at 7 to a clampingmember 8 on one side ofs'aid clamping member. The clamping member 8comprises a plate 9 that is pivoted to the lever 6 and a detachableplate 10 that is secured" to the plate 9' by means of bolts .11

Patented Au 24', 1915 which have nuts 12 turned on their threadedterminals.

l The clamping member 8 is designed to engage and clamp upon the rod 4at a point adjacent the upper end of said rod. The I lever 6 is bowed asat 13 at a point between one end and the pivot point 7 thereof and atthe free end of said bowed portion 13 is secured a brake shoe 14 that isapproximately U-shaped in cross section and engages the cable 1. Thecurving of this lever 16 brings the free end of the curved portion intoa position, so that the shoe 14 will be brought to bear against thecable 1.

A helical retractile spring 15 is secured to one end as at 16 to the rodor bar 5 and at its other end to an eye 17 carried on the bowed portion13 of the lever 6. This spring 15 normally holds the brake shoe 14 intobraking position. A hook designated lever 6, said end being notched asat 19' so as to receive the lower part of the hook and securely holditself in position. The bowed portion 13 isofiset so as to not interferewith the spring 15 or adjacent parts of the carrier. r i

p In operation when it is desired to release the brake from position asshown in Fig. 1, that is, braking position, the lever 6 is movedupwardly and the notched end 19 thereof placed within the hook 18. Itwill be readily seen that the carrier will be held against movement ifdesired by the use of my improved brake.

Inpractice, I have found that the form V of my invention, illustrated inthe drawings and referred to in the above description, as] the preferredembodiment, is the most ,efiie Copieso! this patent may be obtained forI cable.

tion and arrangement of parts may be resorted to, when required, withoutsacrificing any of. the advantages of my invention as set forth.

1 What is claimed is V 1. In a brake the combination with a cable, and'apulley or wheel arranged to run on the cable, of a carrier suspendedfronr the pulley or wheel and a brake lever pivoted-jat a pointintermediate of its ends to the carrier at'a point below the axis of thepulley or wheel and provided at one, end with a shoe arranged to engagethe under side of the cable belowthe pulley or wheel to cooperatetherewith in clamping. the said 2. In a brake the combination with acable, and a pulley or wheel arranged to run on the cable, of a carrierincluding a supporting bar depending from theipulley or wheel and ahorizontal barconnected with the supporting bar, a clamp secured to thesupporting bar below the horizontal bar and provided with a pivotlocated below the axis of the pulley or wheel, a brake lever fulcrumedat an intermediate point on the said pivot andprovided at one end withmeans V, FRED.
